Endosymbiotic bacteria nodulating a new endemic lupine Lupinus mariae-josephi from alkaline soils in Eastern Spain represent a new lineage within the Bradyrhizobium genus

Lupinus mariae-josephi is a recently described endemic Lupinus species from a small area in Eastern Spain where it thrives in soils with active lime and high pH. The L. mariae-josephi root symbionts were shown to be very slow-growing bacteria with different phenotypic and symbiotic characteristics from those of Bradyrhizobium strains nodulating other Lupinus. Their phylogenetic status was examined by multilocus sequence analyses of four housekeeping genes (16S rRNA, glnII, recA, and atpD) and showed the existence of a distinct evolutionary lineage for L. mariae-josephi that also included Bradyrhizobium jicamae. Within this lineage, the tested isolates clustered in three different sub-groups that might correspond to novel sister Bradyrhizobium species. These core gene analyses consistently showed that all the endosymbiotic bacteria isolated from other Lupinus species of the Iberian Peninsula were related to strains of the B. canariense or B. japonicum lineages and were separate from the L. mariae-josephi isolates. Phylogenetic analysis based on nodC symbiotic gene sequences showed that L. mariae-josephi bacteria also constituted a new symbiotic lineage distant from those previously defined in the genus Bradyrhizobium. In contrast, the nodC genes of isolates from other Lupinus spp. from the Iberian Peninsula were again clearly related to the B. canariense and B. japonicum bv. genistearum lineages. Speciation of L. mariae-josephi bradyrhizobia may result from the colonization of a singular habitat by their unique legume host.

Implementation of safety based incentives in Public Private Partnerships (PPPs): an empirical analysis for the case of Spain

Public Private Partnerships (PPPs) are mostly implemented to circumvent budgetary constraints, and to encourage efficiency and quality in the provision of public infrastructure in order to reach social welfare. One of the ways of reaching the latter objective is by the introduction of performance based standards tied to bonuses and penalties to reward or punish the performance of the contractor. This paper focuses on the implementation of safety based incentives in PPPs in such a way that the better the safety outcome the greater larger will be the economic reward to the contractor. The main aim of this paper is to identify whether the incentives to improve road safety in PPPs are ultimately effective in improving safety ratios in Spain. To that end, Poisson and negative binomial regression models have been applied using information of motorways of the Spanish network of 2006. The findings indicate that even though road safety is highly influenced by variables that are not much controllable by the contractor such as the Average Annual Daily Traffic and the percentage of heavy vehicles, the implementation of safety incentives in PPPs has a positive influence in the reduction of fatalities, injuries and accidents.

Pinus uncinata Ramond ex DC.: Conservation and proposal of management at its southwestern limit of distribution (Castillo de Vinuesa, Soria, Spain)

Pinus uncinata forms forests in the centre and southwest of the Alps and in the subalpine Pyrenees (at around 1700 – 2600 m) (Costa Tenorio et al., 1997). The species reaches the southwestern limit of its distribution at the top of Mount Castillo de Vinuesa (Soria, Spain). The small population on this mountain occupies just 66 ha, but is very important from a geobotanical viewpoint since it is just one of two populations (the other being in the Sierra de Gúdar range in Teruel, Spain) isolated from the main area where the species is found in the Iberian Peninsula (The Pyrenees)

Correlating a documentary record of historical floods with the dendrochronological dating of a wooden decking in the old mint of Segovia (Spain)

the aim of this study is to apply an integrated methodological approximation where dendrochronology and documentary analysis allow us to reconstruct the historical flood record of the Segovia Mint. Our hypothesis is that differences between the dendrochronological data of the wooden decking pieces can be related to historical floods and, therefore, they could be used as proxy-source data in future palaeoflood research.

How has Spain become a leader in the wind energy industry during the last decade?

During the last decade, wind energy has been the fastest growing renewable source of energy worldwide. Limited sources of fossil fuel in addition to the negative effects of greenhouse gas emissions on the environment have led many countries to support development of renewable energies such as wind energy. Spain as the fourth biggest producer of wind energy plays an important global role in wind industry. In this paper, some important factors in the rapid growth of wind energy in Spain such as policy design, industry and technology, economic environment and social acceptance have been studied. The objective of this study is to introduce a model based on the successful development of wind energy in Spain which can be implemented by other countries

A location model proposal for collecting used portable batteries in Spain

The main objective of this paper is to propose a model for helping logistics managers to choose the appropriate location points in order to situate the collection points for used portable batteries. The proposed model has two parts: a static part and a dynamic part. We can conclude that this model helps managers in the decision of locating/modifying collection points in two ways: to add new collection points to a reverse logistics network that needs more points or to delete collection points from a network that has more points than those recommended.

Social involvement for community development in rural areas of Cuenca, Spain

Community development must be accompanied by a social involvement process which creates functional groups of citizens capable of taking responsibility for their own development. It is important that this process promotes the structuring of all population groups and provides the appropriate institutional and technical support. The present paper addresses these issues based on over 25 years of experience by the Association Instituto de Desarrollo Comunitario de Cuenca in revitalizing rural areas of the Spanish province of Cuenca. This paper analyses the social involvement process encouraged by this association, the relationships between public institutions and local associations, the role of these associations and the difficulties encountered in the rural areas. The long-term perspective of this experience provides some keys which can be used to successfully support the process of social involvement ―such as information on its characteristics and methodological tools―, establish local associations and create sustainable partnerships that foster the growth of leadership within the community development process.

Continental Perspective 3, Spain

Well, I firmly believe that, as a professor, one has the duty, the obligation to show and explain his work. Not, of course, as a model to imitate, but rather as an opportunity to reflect upon that work. So, I will try to explain some of the considerations that were crucial in the development of each project. It is my hope that these reflections may be of interest to you, and due to my optimistic nature, that you may even enjoy it. Today I am going to present some projects, from a specific point of view: that of MATERIALITY. This is why I decided to title this presentation ARCHITEXTURE: that is, architecture from the point of view of texture, the quality of its material. Our architecture wants to pay attention to materials; we like to use very physical materials. We try to explore the expressive possibilities of different materials. That allows us, on the one hand, to try to master different techniques, and exploit their potential. On the other hand, it also avoids the dangers of style. Style is the death of an architect. When he starts repeating formulas, avoiding experimentation, copying himself, he dies of boredom, of intellectual boredom. Nevertheless, I don’t believe that the material itself determines anything. Architecture is an exercise of the freedom of an architect. Almost nothing is a given. Of course, there is the law of gravity and economic restraints, and even the overwhelming building code. But the most determinant factor is always the freedom of the architect, derived from his mastery of knowledge and culture, and his decision to innovate and to take risks

Virtual Learning Environments In Faculties Of Education In Spain: Changes On Student Attitude

This paper presents some results of a R+D project entitled “e-Learning system for Practical Training of University students in Education Faculties (ForELearn)”, developed in Spain by the Universidad de Granada and the Universidad Politécnica de Madrid and funded by the Spanish Ministry of Education. In a first phase, through the use of AulaWeb Learning Management System, a set of adaptations and improvements of this software application have been done for the design and development of an experimental course of Practicum supervision. Next, the implementation of this course by means of a group of face to face and online seminars provides experimental data for the analysis and discussion about the point of view of users (preservice teachers) that have tracked their practice supervision with AulaWeb.

Lupinus mariae-josphi, a new lupin endemic of soils with active lime and high pH in South Eastern Spain, is nodulated by a new bacterial lineage within Bradyrhizobium genus

Lupinus mariae-josephi is a recently described species (Pascual, 2004) able to grow in soils with high pH and active lime content in the Valencia province (Spain). L. mariae-josephi endosymbionts are extremely slowgrowing bacteria with genetic and symbiotic characteristics that differentiate them from Bradyrhizobium strains nodulating Lupinus spp. native of the Iberian Peninsula and adapted to grow in acid soils. Cross-inoculation experiments revealed that all the endosymbiotic isolates from L. mariae-josephi tested are legume-host selective and are unable to nodulate species such as L. angustifolius, and L. luteus. In contrast, Bradyrhizobium strains from Lupinus spp. tested were able to nodulate L. mariae-josephi, although the nodules fixed nitrogen inefficiently. Phylogenetic analysis was performed with housekeeping genes (rrn, glnII, recA, atpD) and nodulation gene nodC. Housekeeping gene phylogeny revealed that L. mariae-josephi rhizobia form a strongly supported monophyletic group within Bradyrhizobium genus. This cluster also includes B. jicamae and certain strains of B. elkanii. Contrarily, isolates from other Lupinus spp. native of the Iberian Peninsula were grouped mainly within B. canariense and two B. japonicum lineages. Phylogenetic analysis of L. mariae-josephi isolates based on the nodC symbiotic gene defined a solid clade close to isolates from Algerian Retama spp. and to fast-growing rhizobia.

Spatial and temporal precipitation patterns of the Ebro River Basin, Spain

The Ebro River Basin, with around 85 000 km2 and located in NE Spain, is characterized by the high spatial heterogeneity of its geology, topography, climatology and land use. Rainfall is one of the most important climatic variables studied owing to its non-homogenous behaviour in event and intensity, which creates drought, water runoff and soil erosion with negative environmental and social consequences. In this work we characterized the rainfall variability pattern in the Ebro River Basin using universal multifractal (UM) analysis, which estimates the concentration of the data around the precipitation average (C1, codimension average), the degree of multiscaling behaviour in time (? index) and the maximum probable singularity in the rainfall distribution ( s). A spatial and temporal analysis of the UM parameters is applied to study the possible changes. With this porpoise, 60 daily rainfall series were selected from 132 synthetic series generated by Luna and Balairón (AEMet). These daily rainfall series present a length of 60 years, from 1950 to 2009. Each one of them was subdivided (1950?1970 and 1980?2009) to analyse the difference between the two periods. The range of variation of precipitation amounts and the frequency of dry events between both periods are discussed, as well as the evolution of the UM parameters through the years.

Some past decision theory models for euro construction model codes and for road drainage in Spain, and modest hints with multi-criteria methods for agro and environmental assurance

The authors are from UPM and are relatively grouped, and all have intervened in different academic or real cases on the subject, at different times as being of different age. With precedent from E. Torroja and A. Páez in Madrid Spain Safety Probabilistic models for concrete about 1957, now in ICOSSAR conferences, author J.M. Antón involved since autumn 1967 for euro-steel construction in CECM produced a math model for independent load superposition reductions, and using it a load coefficient pattern for codes in Rome Feb. 1969, practically adopted for European constructions, giving in JCSS Lisbon Feb. 1974 suggestion of union for concrete-steel-al.. That model uses model for loads like Gumbel type I, for 50 years for one type of load, reduced to 1 year to be added to other independent loads, the sum set in Gumbel theories to 50 years return period, there are parallel models. A complete reliability system was produced, including non linear effects as from buckling, phenomena considered somehow in actual Construction Eurocodes produced from Model Codes. The system was considered by author in CEB in presence of Hydraulic effects from rivers, floods, sea, in reference with actual practice. When redacting a Road Drainage Norm in MOPU Spain an optimization model was realized by authors giving a way to determine the figure of Return Period, 10 to 50 years, for the cases of hydraulic flows to be considered in road drainage. Satisfactory examples were a stream in SE of Spain with Gumbel Type I model and a paper of Ven Te Chow with Mississippi in Keokuk using Gumbel type II, and the model can be modernized with more varied extreme laws. In fact in the MOPU drainage norm the redacting commission acted also as expert to set a table of return periods for elements of road drainage, in fact as a multi-criteria complex decision system. These precedent ideas were used e.g. in wide Codes, indicated in symposia or meetings, but not published in journals in English, and a condensate of contributions of authors is presented. The authors are somehow involved in optimization for hydraulic and agro planning, and give modest hints of intended applications in presence of agro and environment planning as a selection of the criteria and utility functions involved in bayesian, multi-criteria or mixed decision systems. Modest consideration is made of changing in climate, and on the production and commercial systems, and on others as social and financial.

Considerations on the success rate in aeronautical engineering studies in Spain

The relationship between different learning evaluation methods and the academic success in an aeronautical engineering degree in Spain is analysed. The study is based on data about the evolution of academic achievement obtained along the last ten year, along which the evaluation and learning’s methods have suffered huge changes.

Comparación de dos métodos para la estimación de los daños por sequía en pastos de dehesa / Comparative methods for assessment of dehesa pasture drought insurance in Spain

El Sistema de Seguros Agrarios con el Seguro de cobertura de los daños por sequía en los pastos aprovechados por el ganado en régimen extensivo (línea de seguro 133) aplica la teledetección mediante un índice de vegetación (NDVI), con el fin de solucionar los problemas de peritación que surgen cuando se tiene que determinar la cantidad y calidad del pasto afectado por la sequía. Por ello el seguro de cobertura de los daños por sequía en pastos es el principal instrumento para hacer frente al gasto que supone la necesidad de suplemento de alimentación del ganado reproductor debido a la sequía. En las comarcas de Vitigudino, Trujillo y Valle de los Pedroches (España) se comparó la evolución del seguro de sequía en pastos desde 2006 a 2010 con un modelo matemático de crecimiento del pasto en función de las variables ecofisiológicas y ambientales. Sumadas las decenas de sequía extrema y sequía leve, el modelo matemático contabilizó un número mayor de decenas que las proporcionadas por Agroseguro. La recomendación es comparar las curvas de crecimiento del pasto con las curvas de evolución del NDVI, para ajustar ambos modelos

Caracterizacion de la sequia en pastos anuales en Dehesas / Characterization of pasture drought in dehesas of Spain

La sequía es un término meteorológico que significa un periodo seco prolongado. El objetivo de este trabajo es caracterizar el fenómeno estacional de la sequía en pastos anuales de dehesa. Durante 2010 y 2011 se realizó un seguimiento del pasto herbáceo en El Cubo de Don Sancho (Salamanca), Trujillo (Cáceres) y Pozoblanco (Córdoba). Se midió la producción herbácea y se caracterizó botánicamente cada zona, además se midió mensualmente la variación del contenido de agua en el suelo mediante un TDR y la precipitación. Los datos de campo de precipitación, humedad del suelo y cantidad de pasto en pie, y los datos estimados de evaporación se han comparado con la evolución del índice de vegetación para seguros de sequía por teledetección determinado por Agroseguro. Los resultados mostraron un retardo entre la acumulación de agua en el suelo y el crecimiento del pasto, que se transfiere a las medidas del índice de vegetación por teledetección. En los dos años de estudio los periodos de sequía sucedieron al inicio de crecimiento, justo después de la sequía estacional típica del verano.
